Title: Premixing method in low nox premixing combustion device
Inventor: MASAI TADAHISA
IPC: F23R3/30
Filed: 1992-07-31
Abstract: PURPOSE:To provide a premixing method for a gas turbine combustion device capable of getting a quite uniform premixed gas through its dispersion mixing and further capable of accomplishing a substantial low NOx operation. CONSTITUTION:A hollow member 31 is installed in a premixing passage 30 in which a combustion injection flow 40 of premixed fuel and premixed air 7 are dispersed and mixed to each other so as to divide the premixing passage 30. Both side surfaces of the hollow member 31 are provided with mixing and dispersion air openings 32, a mixed dispersion air flow 41 is injected into the premixing passage 30, it is crossed at a right angle with the premixed fuel and premixed air flow to promote the dispersion and mixing to each other and further to get a uniform premixed air. Accordingly, as regards a low NOx formation in a gas turbine combustion device, the premixing combustion is carried out with excessive amount of air so as to decrease a temperature of flame, although in the case that the premixed gas has a difference in concentration, the partial high temperature flame is generated and a low NOx formation can not be attained as expected. With such an arrangement as above, since a quite uniform premixed gas can be attained, a substantial low NOx can be realized.
